Contactor question

[penner]

I accidently ordered the 2 pole 40 amp 240v coil contactor http://www.auberins.com/index.php?main_page=product_info&cPath=2_31&products_id=164 instead of the 2 pole 40 amp 120v coil contactor. I am building http://www.pjmuth.org/beerstuff/images/Auberin-wiring1-a4-5500w-BIAB-30d6.jpg. Will I be ok or do I need to have the 120v coil?

Thanks to PJ for all of your hard work. I would never have been inspired to try an a e-brewery without you and all the knowledgeable people in this forum.

Sure, you just need to make minor adjustment to the diagram. Connect a second coil terminal to another hot instead of neutral.

I think just connecting the other hot to the other side of the coil would cause the LED to always be on, including the coil to always have 120V across it.

If switch 1 has two NO contacts you can connect 240V contactor this way:

the last two pages of this thread might help as I believe you made the same mistake as one of the posters here... he post diagrams of how he fixed it.

I have an extra NO block laying around. I believe I can make this work.

Thanks!

My solution is very similar to that one. Mine just a little bit simpler and safer.
